Carbon dioxide and scale insects
 

I recall that there was a thread a while back on using CO2 to get rid of
scale and other insect pests. The idea was to put the plant in a 100%
CO2 atmosphere for some length of time. The insects, being animals and
needing oxygen, would die.

Has there been any more information made available about this technique?
Anyone tried it?

I've not tried it myself, but apparently it works. IIRC, it involved
putting the affected plant into a sealed 5. gal plastic bucket with
pellets of dry ice-- care being taken to avoid direct contact between
the dry ice and the plant. IIRc, again, it took several hours to work.

I'm sure somebody else will have a more detailed and helpful
description of the technique.

Before I bring my plants in for the winter I spray them with an
effective scale killer and an IGR ( insect growth regulator) No scale
this year--so far.

Isn't that the best fragrance? Just love it. Does the white one you bought
have any color at all in it?

No.

Jadel, I read that putting the dry ice in water makes a visable fog
that is easy to see the CO2 level in the container. I plan to run my
50 thru the process when I move them outside for the summer. More
later.

If you're planning a longer term exposure, put some chunks on a meat tray
as well.
And if I'm remembering my atomic weights... 44grams of dry ice should give
you 22 liters of gas.

Are the plants infested now? If not, therre's no reason to give them
the CO2 treatment before you put them outside. CO2 has no residual
effect; it won't protect them from infestation outdoors.

A pound dry ice = 8.3 cubic feet carbon dioxide gas.
Metric
0.453 kilogram dry ice = 235 liters carbon dioxide gas.

A mole of anything will produce 22.4 liters of gas at STP. 44 grams is a
gram-mole, so the original conversion was very close to correct.

Likewise, 453 grams is 10 moles, so...
